1. crow, that is brilliant

I could only hope to figure out how skinning in potential layers is really done in such beauty! Another excellent study material for a neophyte skinner like me!
2. Freedom of speech is not an absolute right. It applies so long as it is in alignment of the fundamental constitutions of universal democracy. Nazism is politically and officially an undemocratic ideology which promotes racism, discrimination, and right-wing terrorism. Only the USA allows the freedom of speech to outright Nazism followers. In the USA, the potential grounds for filing a lawsuit against Nazism is not about its political background, but on obstruction of property or mental damages. All other countries limit the freedom of Nazism on the grounds that allowing free speech for Nazism is a self-denial to democratic beliefs.
3. The "swastika" is an ancient symbol found in many religions: far-east, middle Asia, ancient pagan symbols of the Germans, Indo-Aryans, Slavs, Vikings and etc etc. Thus the historicity or the meaning of a certain symbol is to be derived/judged upon what context it is used. The "swastika of the moon" that is used in Finnish airforces, though identical in image, is in different color and symbolizes different things. It has a different context. Therefore, it is generally accepted the Blue Cross of the Finns is in totally different meaning from the black swastika of the Germans. If the black swastikas would be used on German planes, it would mean Nazism in both symbol and context. Therefore, the black one is rejected, while the blue one is accepted.
